Dear Xx. Xxxxx:
Attached is an updated evaluation on the Xxxxx oil lease located in
Section 30-T34S-R17E, Xxxxxxxxxx County, Kansas. The appraised value is
estimated at $447,144.00. The effective date of this appraisal is April 11,
2000.
This appraisal is based on a working interest of 25% and a net revenue
of 18.75%, which is owned by Keystone Silver Mines, Inc. An oil price of $25.00
per barrel was used and the appraisal is on a non-escalated basis, where price
and the expenses were kept constant throughout the life of the property. The
economic life of the property is estimated to be 11 years.
The producing formation is the Red Fork Sandstone. This lease has
produced 20,000 barrels of oil. Combined primary and secondary operations should
recover an estimated 191,000 barrels of oil. Reservoir characteristics, such as
porosity and permeability, indicate that the formation will flood successfully.
The initial phase of secondary recovery would be a waterflood, followed by a
polymer augmented flood. It is anticipated that the polymer flood would plug the
thief zones and improve the areal and vertical sweep efficiency of the
reservoir. This would result in increased oil recovery that otherwise would not
be recovered.
If you have any questions please let me know.
Sincerely,
/s/ Xxxxxx X. Xxxx
